So I bought Far Cry 3, Bioshock Infinite, and Deadspace 2 for my pc. I've downloaded Far Cry 3, and the only way I can play it is with the settings being configured to low with it running at 25-35 fps. My computer has 8G of ram, an amd radeon hd 6670 with 1g of memory, and a quad core processor that runs at 3.6GHz. Are there any settings I can use on my graphics card in the control panel to speed up the game? Will I be able to run Bioshock Infinite and Deadspace 2 at a confortable fps? What settings should I use in the game? (Vsync, windowed or fullscreen, CPU frame buffer, etc)
